For earlier Avalon 900 and Lopi FoxFire and 400 models, refer to the 1994 Pellet Troubleshooting Guide. Who Should Use this Guide This guide was developed for service personnel and those selling Travis Industries products. Because of the inherent danger involved with heating appliances, all work must be done by qualified personnel only. The heater must be installed in accordance with the owner's manual and all local building codes. Bring an owner's manual for the heater being serviced in case any installation or maintenance questions arise. Precautions This heater becomes very hot during operation - use care to prevent burns or property damage while servicing. Make sure the appliance is unplugged before conducting service or replacing a component. Some procedures may require the heater to be plugged in while diagnosing the problem. In these cases, use caution to prevent arcing or electrical shocks. Before conducting service, lay down a drop cloth to prevent flyash and other debris from staining the carpet or other flooring. On inserts, lay down a piece of cardboard on the hearth to prevent scratches. How to Use this Service Guide When this troubleshooting guide refers to a side or direction, use the diagram to the right to determine direction. Above This guide uses several sections to address pellet stove service. The flowchart section (section 1) details the troubleshooting process from start to finish. Section 2 addresses each troubleshooting step individually (if you know the problem, you may wish to go directly to the troubleshooting step). Section 3 is dedicated to removal and replacement instructions. Section 4 contains technical specifications.

Unless the true problem is found, conducting service may only provide a slight performance increase. Often, when a part is exchanged with a new part, the stove's performance will improve enough to operate at a low performance level. For example, if you install a new exhaust blower you may improve performance enough to let the stove burn. But unless you clean the stove and show the customer how to maintain a clean stove, you will not fix the real problem. This stove with a "false fix" may work for several months, only to fail again. To eliminate false fixes and help make correct diagnosis, keep in mind these principles when diagnosing pellet stoves: Treat the Pellet Stove as an Entire System Air leaking through the door seal will decrease performance; a dirty stove will decrease performance; poor pellets will decrease performance: before you leave a service call, make sure all aspects of the pellet stove are working correctly. Just because you fixed a door leak does not mean that you should not check for flyash buildup. Test Components Individually Before replacing a component, test it against a new component. This is especially important for blowers and auger motors. Simply plug them in directly to a hotwire and compare performance. Test the Stove Thoroughly Before leaving a customer's home, make sure to operate the stove for at least one-half hour. Use the time to clean up or finish paperwork. Furthermore, test the stove on various burn rates to ensure proper operation. Know the Stove's Performance Level Become familiar with how a brand new stove performs. Check the flame quality (on high and low), heat output, blower noise, blower cfm, air wash, normal ash buildup, and door seal. Everything should be noted. With a new stove as a benchmark, you can test a customer's stove for relative performance. The 5 Most Common Problems Before leaving a service call, make sure the following items have been checked: ¥ Air Leaks ¥ Dirty Stove © 1998 Travis Industries, Inc. ¥ Jammed Auger 93508201 ¥ Poor Pellets ¥ Blocked Vent 040301 Go to Main Menu iv Introduction Warranty Procedure Most components inside Travis Industry stoves are warranted. To receive credit for a component covered on the warranty, follow the PRA (P roduct R eturn A uthorization) procedure below: 1) Fill out a PRA form (white, pink, & gold carbon paper form) - keep the gold copy for your records. 2) Send the form, along with the component, to Travis Industries, Attn: PRA Returns, 15530 Woodinville Redmond Road, Suite # 300, Woodinville, WA 98072. 3) When it is tested defective, you will receive full credit. 4) Order a new component (if needed to replace existing stock). NOTE: The items must be defective and under warranty to receive credit. If the component is tested and found to be workable, or if it is not under warranty, it will be returned to you at your expense.

Flowcharts 93508201 040301 Go to Main Menu Troubleshooting Steps 2-1 Clinkers If the flames are coming only from the sides, or are orange and black, turn the stove off and check for clinkers. Clinkers are hardened clumps that form over the air holes inside the firepot. The most likely causes are: ¥ Poor pellet quality ¥ The door or glass has an air leak ¥ The stove or vent requires cleaning A A AA A A Make sure the stove has fully cooled (approximately 25 minutes) before conducting service. Cleaning the Firepot To clean the firepot, open the door (see page 23) and knock away any debris on the firepot with a screwdriver. If severely clogged, remove the firepot to gain better access. Use a screwdriver, or other tool, to fully dislodge any clinkers on the firepot. © 1998 Travis Industries, Inc. A AA A AA AA 93508201 011202 Go to Main Menu Troubleshooting Steps 2-2 Stove Cleaning Ash buildup is the leading cause of poor performance. Excessive buildup can even lead to stove failure. Regular cleaning is required to keep pellet stoves operating. Whenever service is conducted, consider cleaning the stove in front of the homeowner to display how this process is conducted. The four sections of stove cleaning, and the appropriate cleaning frequency are displayed below: Section Frequency Clean the Firebox Twice a Week Ð or Every 10 Bags Clean the Vertical Exhaust Duct Once a Year Ð or Every 2 Tons Clean the Horizontal Exhaust Duct Once a Year Ð or Every 2 Tons Clean the Exhaust Box and Exhaust Blower Once a Year Ð or Every 2 Tons Make sure the stove has fully cooled (approximately 25 minutes) before conducting service. A shop vacuum with a drywall filter (available at most hardware stores) will remove flyash well. The drywall filter prevents the fine ash particles from entering the air. Clean the Firebox a Swing the side ash trap door up. b Lift it up and away from the firebox. Repeat for the opposite side. c Lift the firepot out of its holder. d Slide the ash pan trap door forward to expose the ash dumps. e Brush all flyash into the ash dumps, including the flyash inside the firepot holder. f Replace the ash trap doors and firepot. Slide the ash pan trap door forward. AA AAA AAA AA © 1998 Travis Industries, Inc. AA AA 93508201 011202 Go to Main Menu Troubleshooting Steps 2-3 Stove Cleaning (continued) Clean the Vertical Exhaust Duct The following models have vertical exhaust ducts welded in place. Heritage Bay PS serial # below 211650 Heritage Bay PI serial # below 410650 Avanti PS serial # below 121700 Avanti PI serial # below 320525 To clean, follow the directions below. Vertical Exhaust Duct Use a hammer to tap against the fireback in front of the vertical exhaust ducts (not too hard). This should dislodge loose flyash. Remove the flyash by removing the ash trap doors and sweeping into the ashpan. NOTE: If the flyash does not dislodge, use a bottle brush or other device to scrape the flyash from the ducts. More recent models use the cast-iron fireback as the front of the vertical exhaust duct. To clean, follow the directions below. Remove both refractory side clips. Clean this area behind where the refractory rests (both sides). Remove the refractory. Remove these doors to remove fallen flyash and soot (see ÒBi-Weekly Maintenance for detailsÓ) © 1998 Travis Industries, Inc. 93508201 011202 Go to Main Menu Troubleshooting Steps 2-4 Stove Cleaning (continued) Clean the Horizontal Exhaust Duct a Open the hopper lid and remove the two screws holding the side doors in place.

Exhaust Box Blower Blades Exhaust Motor d © 1998 Travis Industries, Inc. 93508201 Gasket Blower Housing Clean the blower blades, blower housing, and exhaust box. You may wish to use a vacuum to pull ash out of the vent system. 011202 Go to Main Menu Troubleshooting Steps 2-5 Blocked Vent Flyash that has been expelled by the exhaust blower will accumulate in the vent sections. Check the locations shown below for flyash buildup, and, if necessary, clean the entire vent system. Make sure the stove has fully cooled (approximately 25 minutes) before conducting service. Make sure the cap is free of debris (especially if it has a screen that could become blocked). AA AA AA AA AA AA Check the vent sections for creosote accumulation (indicating a poorly burning stove). Accumulation over 1/4Ó must be removed. Flyash will deposit along sections that are horizontal. On vertically vented systems, the dirtiest portion is often the point where the vent turns upwards (i.e. the "Tee"). Fortunately, the "Tee" has a built-in clean out cover. Remove the cover and vacuum out. While open, use a flashlight to look up the pellet vent to check for build-up. Restrictor Adjustment In some cases the vent will produce too much draft for the stove. This leads to an inefficient burn, and in some cases, the flame going out. Excessive draft typically happens in tall vertical installations or very short horizontal installations. The factory restrictor setting is wide open. When to Adjust the Restrictor ¥ If un-burned pellets are expelled from the firepot often (make sure they are un-burned, not just cylindrical embers), the restrictor needs adjustment. ¥ If on LOW the pellets burn too quickly and the flame goes out, the restrictor needs adjustment. How to Adjust the Restrictor c Use these index marks to gauge restrictor movement. Move the restrictor one position, then inspect the stoveÕs performance over a long period of time. NOTE: You will not notice much change in the flame after adjusting the restrictor. Check stove performance over a long period of time. 7/16" Wrench Air Inlet Restrictor mb u Air stio n a WARNING: The stove must be completely cool and unplugged prior to beginning this procedure.

Follow the directions below to diagnose and fix any air leaks. Checking the Door Seal Close the door on a dollar bill (or a piece of paper). Then try pulling the bill out. If it comes out easily, the door gasket is not forming a seal. Repeat this process around the perimeter of the door to ensure a complete seal. If the seal is inadequate, check the door gasket. If it is flattened, or does not protrude at least 3/16" from the door frame, replace the door gasket. If the gasket is adequate the door will require adjustment. AA AA AA To check the glass seal, press on each panel of glass. If the glass moves easily, the glass gasket has become displaced or damaged. To fix the glass seal, disassemble the door and re-assemble, ensuring the glass gasket is properly placed. AAA AAA Replacing the Door Gasket Make sure the stove has fully cooled (approximately 25 minutes) before conducting service. Use only Travis Industries gasket when replacing the door gasket. 1 Remove the decorative trim above the door by opening the hopper and removing the two screws holding it in place (use a phillips-head screwdriver). 2 Remove the door by unlatching it, opening it wide open and lifting it straight up off the hinge mounts. You may need to swing the door back and forth to loosen the hinge pins. 3 Place the door on a flat, soft surface with the inside of the door facing upwards (do not scratch the gold). Find the beginning of the gasket, usually near a corner, and pull it away from the door assembly. Prepare the surface for the new gasket by scraping off any large pieces of debris with a flat-head screwdriver, scraper, or wire brush. Remove any loose particles. 4 Apply a liberal amount of the gasket cement around the area where the new gasket will lie. 5 Apply the new gasket onto the gasket cement. Start in the bottom corner near the hinge. Be careful not to bunch or stretch the gasket. Make sure the corners lie flat. The gasket is cut to fit the door - there should be little or no excess length (at most 3Ó). Start the gasket in the bottom corner near the hinge. AAA AAA AAAAA AAAAAAAA AAA A AAAAAAAA AAAAA AAAAA AAA AAAAAAAA AAAAA AAAAA AAA A AA AAA AAAAA AA AA AAA AA AA AA AA AA AAAAAA AA AA AAAAAAA Make sure the gasket is flat around the corners. New Gasket NOTE: Do not bunch or stretch the gasket - this will make the gasket uneven, or too thin - leading to air leaks. Gasket Cement 6 Wipe any excess adhesive off all free surfaces and let the adhesive set about 30 minutes. 7 Re-attach the door assembly and decorative trim Close the hopper lid. © 1998 Travis Industries, Inc. 93508201 011202 Go to Main Menu Troubleshooting Steps 2-7 Air Leaks (continued) Door Adjustment The door latch plate and hinge plate are adjustable, allowing the door to be pulled in closer to the stove. These plates have notches that line up with dimples on the side of the stove. To adjust the door, loosen both plates and move them back 1/16". Use the notch and dimple to ensure correct alignment (so the door does not tilt up or down). Recheck the door seal after each adjustment. If you notice the door is tight against one side, but loose against the other, tighten only the side that is loose. a HINT: Open the hopper and look down at the door from above. Make sure the door is properly aligned and is evenly spaced away from the face of the heater. Open the hopper lid and remove the two screws holding the side doors in place.

Check the items below to ensure the trap door is sealing. b Clean the trap door and underside of firebox. Slide the trap door back in place. Trap Door a Pull the trap door out. Carefully inspect it to make sure it is not warped. c The trap door is pressed against the firebox with this pressure plate. If the trap door does not press firmly against the firebox, tighten the four nuts on the pressure plate appropriately. Air Inlet Blocked In rare cases the air inlet becomes blocked. Snow or debris can clog the opening. The flexible aluminum duct can be flattened. To verify the air inlet is functional, remove the air inlet hose from the stove. If stove performance improves dramatically, the air inlet may be restricted or blocked. © 1998 Travis Industries, Inc. 93508201 011202 Go to Main Menu Troubleshooting Steps 2-9 Faulty Exhaust Blower The exhaust blower pulls air through the air inlet, burnpot, and exhaust ducts. If these channels are blocked or restricted, performance will decrease. Therefore, before checking the exhaust blower, make sure the stove is clean. Make sure the stove has fully cooled (approximately 25 minutes) before conducting service. Unplug the stove to prevent electrical shock. The only way to check the exhaust blower is to remove it from the stove, hotwire it, and compare it to a new exhaust blower. See the directions below. Use a hot-wire to check blower performance (you should do this outside to prevent stray flyash from entering the home). Be careful to not touch the impeller. Gauge the airflow leaving the blower. Fuse Blown Make sure the stove has fully cooled (approximately 25 minutes) before conducting service. Unplug the stove to prevent electrical shock. The fuse is located at the back of the stove near the location where the power cord connects. There are two different types of fuse holders: There are two fuses on the pellet stove. An in-line fuse is found at the rear, near the power cord. Fuse (part # 93-0695) Fuse Holder A circuit board fuse is found on the back of the circuit board. See the section ÒCircuit Board FaultyÓ for details. This type unscrews with your fingers. Press in slightly while turning the fuse holder counter-clockwise to release.

Pellets, left over the summer, can absorb water, expand, and jam the auger. Pellets piling up inside the burnpot can fill the drop tube and then jam the auger. Foreign objects left in the hopper can jam the auger. To remove the auger flight inspection plate and clear any items jamming the auger, follow the directions below. NOTE: on pellet inserts, remove the hopper cover before conducting the following steps. a Remove all pellets in the hopper. b Remove the silicone shown here (the silicone shown in gray need not be removed). c Unscrew the six screws holding the auger flight inspection cover in place. 5/16" Nutdriver d Remove the bearing cover and auger flight inspection plate.

Unplug the stove to prevent electrical shock. Hopper Snap Disk The auger circuit consists of the auger motor, flow switch, hopper snap disk, and the wiring between. If the auger motor is not receiving electricity during normal operation, you should check the auger circuit for malfunctions. The first step is to check the wiring. Make sure no wires have been pulled loose, severed, or melted. Check the four red wires leading to the hopper snap disk and flow switch. Check the red and white wires leading to the auger motor. Disconnect each quick-connect and re-connect, making sure full contact is made. Flow Switch Auger Motor Next, check the flow switch and hopper snap disk. These safety components were designed to disable the auger motor in the event of a malfunction. The hopper snap disk disables the circuit if the hopper becomes too hot. The flow switch disables the circuit if the vent becomes blocked. Follow the directions below to test the flow switch. a Unplug the stove. b Disconnect the two wires leading to the flow switch. c Attach a jumper wire to the two wires removed. d Back of Flow Switch Turn the stove on and test operation. If the stove still does not work, replace the wires and test the hopper snap disk (see the directions below). If the stove does work, the flow switch is not working. Make sure the vacuum hose is attached at both ends and in good shape. Replace the flow switch if the hose is correct. Vacuum Hose Follow the directions below to test the hopper snap disk. a Unplug the stove. b Disconnect the two wires leading to the hopper snap disk. c Attach a jumper wire to the two wires removed. d Turn the stove on and test operation. If the stove works normally, the hopper snap disk is malfunctioning and should be replaced. If the stove still does not work, see the section for testing the circuit. board. CONTINUITY Hopper Snap Disk (on the right side of the hopper near the top) © 1998 Travis Industries, Inc. 93508201 If you do wish to test the snap disk, heat the back side of the snap disk with a lighter.

Because pellets are made from wood by-products, pellet manufacturing is dependent upon the supply of these by-products and the quality found therein. Unfortunately, this surge in pellet manufacturing has led to a decline in the quality of the raw materials used to produce the pellets. Ideally, pellets should have a very low moisture, ash, dirt, and salt content. Some pellets do not. Pellets should have a consistent diameter of 1/4", 5/16", or 7 mm. Pellets should also be no longer than 1 1/2" long. Some pellets are longer. There is no real pellet monitoring agency, so you must monitor pellet quality yourself. Pellets left outside in damp conditions may absorb water, decreasing performance. Poor pellets may lead to the symptoms listed below. Poor quality pellets may lead to clinkers in the firepot (look for dark spots on the burn grate while the stove is burning) AA Recommendation: Poor quality pellets may lead to dirty glass, especially if it is black and sooty Poor quality pellets may lead to excessive flyash, making the stove require more frequent cleaning Poor quality pellets may lead to the auger jamming frequently AAA AAAA AA AAA AAAA Bring 3 bags of pellets that you have tested and are high quality. Let the customer burn the pellets and check for these signs of bad pellets: clinkers develop in the air holes on the bottom of the firepot; the auger jams for no apparent reason, and when the hopper is cleaned out, the auger runs again; there is more than one-half cup of sawdust in the bottom of the bag of pellets; or, the pellets don't burn well on a low burn rate. It is best to check one brand of pellets versus another to see the difference first-hand. The Association of Pellet Fuel Manufacturers has set the following standards for pellets: density of at least 40 lbs. per cubic foot; 1/4" to 5/16" diameter; length no greater than 1 1/2"; 8200 BTU's/lb.; moisture under 8% by weight; ash under 1% by weight; and, salt under 300 parts per million. © 1998 Travis Industries, Inc. 93508201 011202 Go to Main Menu 2 - 16 Troubleshooting Steps Noisy Stove Normal Operating Sounds Before conducting a service call for a noisy stove, try to quantify the amount of sound coming from the stove. Pellet stoves have several components with moving parts that will create noise. You may wish to go over the normal operating sounds with the customer before conducting a service call. Exhaust Blower The flow of exhaust gases may create a low-pitched hum. This sound will change as the FEED RATE is altered. Auger Motor When feeding pellets, you may hear the intermittent buzz of this motor running. Heat Exchanger Tubes You may hear the heated air being forced through these tubes by the convection fan. Covection Fan The modern high efficiency fan may produce a low hum, particularly on "HIGH". This sound will change as the FAN dial is turned. Firepot As pellets are fed into the firepot, a light clicking sound may be heard. Listen carefully for screws, bolts, or nuts that have become loose. If they are not tight, rattling may occur. Diagnosing Stove Noises Noise may be created by several factors. Moving components (blowers or auger motors) may create noise or a vibration that leads to a rattle. The process of eliminating a noise is to identify which component is creating the noise and either securing it better, placing a piece of gasket to dampen the rattle, or replacing the component. Use the illustrations to the right to help diagnose stove noises. If the noise occurs only when the auger is moving, remove the pellets and check the auger flight to see if anything is caught. If the auger motor "clicks" , check to see if it is knocking against the motor stop. There are two rubber bumpers built into the motor stop designed to stop this noise - make sure they are in place. If a blower is creating noise, try loosening its connection, realigning the blower (& gasket), and re-tightening the connection. Any vibration can lead to noise. On stoves, make sure the side panels are attached. The hearth may ampify any vibration on the stove, especially on uneven or irregular hearth surfaces. If you hear any noise from this area, try attaching gasket tape to the bottom corners of the pedestal. Inserts Make sure nothing has fallen into the convection blower. Make sure the top panel is not rattling against the facing. Use gasket tape to dampen any sound, if necessary. Check the base of the insert. Sometimes, especially on irregular shaped hearths, the hearth can transmit sound from the insert. Wedge a small piece of gasket tape under the insert to eliminate the sound. Make sure the double-back tape holds the trim firmly against the surround panels.

It also performs a necessary cooling function for internal components*. To check the convection blower, follow the steps below. Make sure the stove has fully cooled (approximately 25 minutes) before conducting service. Unplug the stove to prevent electrical shock. a Unplug the stove. b Disconnect the two wires leading to the convection blower. c Attach a a hotwire to the convection blower. Convection Blower (shown here removed) d e Check for air blowing out of the heat exchanger tubes. Air Comes Out - Blower is okay, check the convection blower circuit. With the blower unplugged, check the inside of the squirrel cage thoroughly. Make sure the squirrel cage turns. Debris or pellets can jam the blower. If nothing is found, replace the blower. Air Does Not Come Out - Blower is faulty. Go to step ÒeÓ. Convection Blower * If the convection blower does not work, the stove may overheat, causing the hopper snap disk to disable the auger.
